At the tail-end of last week, General Motors quietly acknowledged that certain early 2017 Chevrolet Bolt EV electric cars had a fault inside their original battery packs which, in General Motors’ own words “lose propulsion before the customer expects.”

But what is the cause of the issue? How is it being identified? And what can you do if you’re a Bolt EV owner worried your car may need a replacement pack?

    My 6-month-old 2018 Bolt lost 40% of its battery capacity. The dealer said it checks out when they scanned it as all systems okay, but now I have a maximum of 138 miles which keeps me from driving to a city to which I frequently travel. The dealerships claimed it was due to cold weather but I store the car in a heated garage. Has anyone else faced this issue?

    Long Life Lithium Ion Tricks

    Avoid Fully Charging
    Avoid High Heat hotter than 77 deg F
    Avoid Parking in Direct Sun
    Avoid Fast Charging (heats battery)
    Avoid Charging when Frozen to 0 deg F
    Avoid Deep Discharge below 10%

    Keep the battery 30-80% charged for long life
    Keep the car around 40-80 deg F as often as possible
    Use Slower L2 charging or L1 charging at home

    Like with a gas (petrol) car though, surely the important issue is whether it is a faulty energy level measurement error, or the actual battery pack has faulty cells losing you range? IE Chevrolet/GM seem to be steering clear of admitting it's c**p batteries, preferring to imply it's a duff 'fuel gauge'? I agree they also are false about the procedure they are offering to cure the fault being 'service'. It's a major fault being done under warranty, concerning the single most important component in the car, and that is a recall in anybody's book. Incidentally, this clears up the first issue almost 100% making it likely not to be a measurement issue but a cell degradation issue. As for it being early models at the moment, that either means the battery cells have degraded over time alarmingly quickly, or that the measurement electronics have. Sounds like they would like to maintain vague ambiguity and say as little as possible all round to me. That's a real car maker of the trad old school – they won't admit to being 'in production hell'. Interesting that the EV owner you mention hasn't clarified whether actual loss of range was involved or just faulty measurement and reporting to the driver.

    I was one of the first Bolt owners in Southern CA and experienced the battery problem. The car showed 40 miles of range remaining when the battery died. Chevy called in tech experts from Detroit and they wound up replacing my battery.
